Well, there's a difference between "clean" ontologies and what people
actually do. Peter Mika from Yahoo! could step in with actual data,
but it appears most people apply hcards and vcard properties to people
or organizations directly, without an intervening (and often blank
node) for the "card" itself.

If someone wants to make a distinction that this particular URI is
actually a "card" or a "person" they can state that using FOAF.

Also, it's much easier to query without tooooo many layers of indirection.
